Answer:

C.ratio of elements in the compound.

Explanation:

A compound is a substance that constitutes two or more elements in a defined proportion. A chemical compound is different from another compound in what it contains i.e. elements. A chemical formula shows the elements contained in a specific compound. For example, the chemical formula of sodium chloride (NaCl) shows us that it contains Sodium (Na) and Chlorine (Cl) elements as represented by symbols.

In addition to this, a chemical formula also shows the ratio of each element that makes up the compound. An element can have more than one atom in a compound. For example, CaCl2 is the chemical formula for Calcium chloride and it shows is that the ratio of Calcium (Ca) to Chlorine (Cl) is 1:2.

The density of benzene is 0.879g/mL. The volume (with 1 decimal) of 131.9g sample of benzene is how many mL?
timurjin [86]

Answer:

150.1 mL

Explanation:

Step 1: Given data

  • Density of benzene (ρ): 0.879 g/mL
  • Mass of the sample of benzene (m): 131.9 g
  • Volume of the sample of benzene (V): ?

Step 2: Calculate the volume of the sample of benzene

Density is an intrinsic property. It is equal to the quotient between the mass and the volume of the sample of benzene.

ρ = m/V

V = m/ρ

V = 131.9 g/(0.879 g/mL)

V = 150.1 mL

Why is Sodium chloride a compound but not a molecule? I thought all the compounds are molecule but not all molecules are compoun
Firdavs [7]
Molecule is the general term used to describe any atoms that are connected by chemical bonds. Every combination of atoms is a molecule. A compound is a molecule made of atoms from different elements.
Well, if a molecule is considered to be a discrete small unit made up of atoms joined together, then NaCl, and any other ionic solid is not really a molecule. In NaCl we have a repetitive crystal structure in which each Na+ ion is surrounded by Cl- ions, and vice-versa, for as far as the crystal extends. There really isn't such a thing as an NaCl molecule.

What’s the answer please
DaniilM [7]

Answer:

5 × 10⁻³ mol

Explanation:

Step 1: Given data

  • Volume of HCl solution (V): 25 cm³
  • Molar concetration of the HCl solution (C): 0.2 mol/dm³

Step 2: Convert "V" to dm³

We will use the conversion factor 1 dm³ = 1000 cm³.

25 cm³ × 1 dm³/1000 cm³ = 0.025 dm³

Step 3: Calculate the moles of HCl (n)

We will use the definition of molarity.

C = n/V

n = C × V

n = 0.2 mol/dm³ × 0.025 dm³ = 5 × 10⁻³ mol
